Nothing special, buy a cheaper beaker. I've come to expect excellence from grav...this is so-so. I added a charcoal filter since it's on 14 mm tubing, and grav makes one in that size. That makes it almost impossible to draw without burning your face. Wish I had put the money towards a better piece.
It’s a great piece. Nice and sturdy.
It's small and, like the other reviewer said, so is the bowl that comes along with it. Swap out the bowl and you have an awesome daily. It does get dirty quick, but as long as you have decent cleaning stuff that is not an issue. 3 minutes cleaning and you're ready to rock and/or roll!
